Bump Azure Stack Terraform Provider for Go 1.18

Needed to bump x/sys dependency due to golang/go#49219
to ensure Go 1.18 compatibility on darwin.

This commit revendors our AzureStack fork to bring in:
openshift/terraform-provider-azurestack#5

which updated x/sys with the following commands:

go get -u golang.org/x/sys
go mod tidy -compat=1.17 && go mod vendor
